Spatial orientation obstacle simulator

Abstract

The invention relates to the technical field of simulated flight, in particular to a spatial orientation obstacle simulator which comprises a transmission supporting system, a rotating arm system, a rolling frame system, a yawing frame system and a cockpit system, wherein the transmission supporting system supports the rotating arm system and drives the rotating arm system to rotate in the horizontal plane; the rolling frame system is arranged on the rotating arm system and rotates around a connecting point of the rolling frame system and the rotating arm system; the rotating center line of the rolling frame system is located in the horizontal plane; the yawing frame system is arranged in the rolling frame system and rotates around a connecting point of the yawing frame system and the rolling frame system; and the cockpit system is arranged in the yawing frame system and rotates around a connecting point of the cockpit system and the yawing frame system. The spatial orientation obstacle simulator has the advantages that a main shaft rotates to generate overload acceleration, three degrees of freedom of yawing, pitching and rolling relative to a human body coordinate system are generated at the tail end of a rotating arm, a trained pilot sits in a cockpit system and bears centrifugal overload acceleration and spatial three-attitude-angle movement, and spatial orientation obstacle simulation training is achieved.

Description

Technical field [0001] The invention relates to the technical field of simulated flight, in particular to a space disorientation simulator. Background technique [0002] A space disorientation simulator is used for space disorientation training. Space disorientation is a major aviation medical problem that seriously threatens flight safety at present, with the characteristics of universality and high risk. In the flight accidents caused by human factors in recent years, the proportion of flight illusion has exceeded the loss of consciousness caused by acceleration. Space disorientation can easily lead to loss of space consciousness, lead to nervousness in pilots, and lead to cognitive errors. If it is not correctly determined and handled, it is likely to cause flight accidents. [0003] Carrying out space disorientation training, that is, creating an environment prone to space disorientation through the simulator, helping pilots to correctly understand space disorientation, takin...

Problems solved by technology

[0006] However, the "four-degree-of-freedom helicopter dynamic flight simulator" in this patent adopts a double-layer layout structure, that is, the main drive motor and reducer are located on the ground floor, and a special basement is required for layout. This disadvantage is that the civil construction is complicated. The cost is high, and it is difficult to install and debug the equipment

[0007] The patented yaw frame and its roll frame and pitch cabin are located at the end of the boom, and are connected by a cantilever—that is, a single-point support structure, which causes a single bearing to be subjected to gravity, centrifuge and overturning moment, and the bearing is stressed Strict, resulting in high cost of bearings, and limits the improvement of product sca
